WTW NitraVis 701-705 IQ (TS)

CarboVis® 701/705 IQ (TS)

Digital, optical senor for the IQ SENSOR NET
CarboVis® 700 IQ (TS): Spectral sensor with integrated ultrasonic cleaning for the chemical-free measurement of the organic load and suspended solids concentration:

Optimal for the measurement of TOC and DOC in the inlet/effluent of municipal wastewater treatment plants.

Thanks to its innovative optics and spectral measuring technique, this is sensor is calibration-free. An optimized referencing ensures an excellent zero point and long-term stability. This ensures reliable measuring results! The maintenance-free WTW ultrasonic cleaning technology reduces the manual cleaning effort to a minimum.
